  1. Can I map more than one drive within the same webdav connection?

    It’s because I store my music on drive W, my pictures on drive X and my videos on drive y.

      1. Hi,

        No actually, my drives are already mapped within my local network. I have drive “w” for music, “x” for pictures and “y” for videos.

        What I would like to do is to map the same drives to my parents computer which is outside my local network (in another town) so through Internet.

        Is this possible?

  3. When editing the files on the NAS through NetDrive, are the files actually locked so that other users on the LAN (home drive) cannot access them at the same time?
